BARK-PEELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 300,996, dated June24, 1884.

Application filed November 3, 1882. (No model.)

[ chine. Fig. 2 is a top view or plan of the same. Figs. 3 to 6 represent the details of the construction.

Wy improved bark peeling machinev consists of three rollers, a b c, of which the feedroller c and the delivery-roller a revolve with like rapidity. The rollers a and b revolve in the same direction. The rollers a and c are provided with noses or projections d, whereas the roller b is provided with corresponding recesses.

The trunk, tree, or part of a tree is fed tothe roller c in any suitable manner-for instance, by means of an endless strap or bandis caught by the said roller c by means of the projections d on the same, and is thrown between the rollers a and b. As these two rollers a and b rotate in the same direction, the wood is caused to continuously rotate in -the opposite direction, during which time the said wood is operated on by special devices applied for this purpose, and described later on in this specih'cation, whereby the rollers ct and b act as anvil or bearing surface or surfaces. As soon as the roller a has made one revolution, the projection or i'iose d to the same seizes the wood which has been operated on and removes the saine from the said rollers a and b, so as to provide room for the next following wood, treeor part of a tree. During the time that the wood is being continuously rotated by the said rollers a and b the same is operated on by a row of hammers e or cutters s, according to the quality or kind of wood operated on and the pur- 50 pose to which the said bark is to be applied. Figs. 3, 4, 5, and 6 represent one of the :forms of the cutters and cutter-holders' emthe logs to the roller c, the projection on said y ployed in my said bark-peeling machine. w

is a hammer of like construction with the hammer represented in Fig. l and marked e, to the end of which said hammerx two cutter-holders, r i, are attached by means of suitable hooks, t.

Figs. 3 anda represent the cutter s and cutter-holder r on an enlarged scale. cutter s is held in correct position in the cutter-holder i'- by -nieans of suitable screws. Guide-rods n are attached to the cutterhold ers 1- in order to correctly guide the said cutter-holders. If the hammer as is raised,the two cutter-holders i r approach each other; but as soon as the said hammer a is allowed to fall and strikes the wood to be operated on, the cutter-holders are forced apart, while the cutters s penetrate the bark and peel or- 7o cut the same from the wood.

The pivot on which the cutter-holders are hungis fixed in a rod, c, which said rod is adjustably connected to the hammer by means of a suitable wedge. This rod o is adjustably attached to the said hammer, in order that the same may be raised by loosening the wedge w, so as to be able to unhook the cutterholders i'. and cutters s with greater facility.

rIhe guide-rods u are so connected to the cutter-holders i" that the latter can be readily released from the same.

I do not claim the construction of the machine generally, as this is of ordinary construction,after the manner of machines of this class.

Having now described my said invention, what I desire to claim and secure by Letters Patent is- In a bark-peeling machine, the combination of the rollers a b c,sup'ported in suitable framework, and driven by suitable power, mechanism, substantially as described, for delivering roller adapted to throw the log to the rollers a and b, mechanism for operating on the bark ofthe log while being rotated by the revolution of the rollers a b, and the projection on the roller cc,for removing the log when peeled, substantially as described.
